Problems solved by technology

The above method requires high positioning accuracy for the two. Due to the heavy weight of the main shaft, the centering of the main shaft is carried out manually by operating the manual hoist. low precision
Secondly, this method takes a long time for the crane. From the start of the centering work to the unloading of the hook, it usually takes about 135 minutes to take up the crane. It requires many operators, at least 5 people are required to operate.

Abstract

The invention discloses a device and a method for centering a wind power generator spindle and a gearbox shaft expansion sleeve. The device comprises a wind power generator spindle support, a gearbox support and a tension machine, the wind power generator spindle support comprises a base and a floating rack in up-down arrangement, the floating rack comprises a mounting seat on an upper layer and a floating seat on a lower layer, a horizontal roller set supporting a wind power generator spindle assembly is mounted on the mounting seat and brings convenience to the wind power generator spindle to horizontally move, and a spring support between the base and the floating seat enables the wind power generator spindle assembly and the floating rack to be in a floating state in the vertical direction. The device and the method for centering the wind power generator spindle and the gearbox shaft expansion sleeve are high in centering accuracy, simple to operate and few in needed personnel.

Description

technical field [0001] The invention relates to a tooling for centering connection of two shafts, in particular to a centering device and method for a wind power generator main shaft and a gearbox shaft expansion sleeve. Background technique [0002] The main shaft of the large wind turbine and the shaft of the gearbox are generally connected by an expansion sleeve coupling. The Chinese Patent Publication No. CN101463799 discloses a wind power generator integrated adjustment device, including a reduction box installed on the base, the high-speed end of the reduction box is connected with the generator, the low-speed end is connected with the wind impeller, and the reduction box It is connected with the generator by a coupling. The coupling includes a coupling expansion sleeve. There is a motor mounting seat on one side of the coupling, and a motor is installed on the motor mounting base. The coupling expansion sleeve The belt is connected to the pulley on the motor. [000...
